HINGE. l

Application filed July 23, 1909.

l cation.

My invention relates to improvements in spring hinges,Y and has for its object the cheapening and strengthening of a hinge; the provision of spring-retaining means, and the construction of a spring hinge in such manner that the pin may be readily removed to separate and reassemble the hinge sections.

In prior hinges of this class, it has been found necessary either to employ a separately pivoted member for retaining the spring under tension, which is interposed between the two hinge sections, or the spring is released each time the pin is removed. The former type of hinge involves a somewhat cumbersome construction, while the sections of the latter type are not readily united when secured in position, by reason of the necessity Jr'or first placing and maintaining the initial tension upon the spring.

Again, with the parts stamped from sheet metal, the bearing portions of the hinge for engaging the pin, ordinarily are restricted in size to the thickness of the metal employed for the stamping; while the pin is relied upon not only ior pivoting the hinge sections, but for retaining the spring in place, thus making the structure integral and non-separable. Thus, in my improved device, the removable or separable leaf of thehinge itself, is so constructedes to maintain the spring mounted thereon, under normal tension, and always ready to be assembled.

I'Iaving theseeatures and requirements in mind, I have devised. a cheap and simple hinge attaining certain distinct advantages over the prior structures with which I am acquainted. I may best describe the irnprovements in connection with the accompanying drawing, wherein Figure I is a front view of a hinge embodying my invention. Fig. II illustrates a slightly modified form thereof". Fig. III is a cross-section on line III-III, of Fig. I; l

Fig.v IV is an end view of the hinge shown in Fig. II. Fig. V is a side view o the Specification of Letters Patent.

spring-retaining section. Fig. VI is a similar view of the co-acting hinge section. Fig. VII showsv the loose pin for connecting the hinges. F ig. VIII is a detail illustrating a modification lof the spring retainingl means; and Fig. IX is another detail indicating the ready separation of the hinge sectionsby the removal of thepin.

Throughout the several figures of the drawings, I have-employed the same character of reference to designate similar parts.

In the types of hinge herein shown, the leaves are stamped from sheet metal, and the knuckles 'or pivotal joints are formed by lugs turned up either interiorly orexteriorly of the blank, while said lugs are inturn anged, not only to secure extended bearings for the pin or pintle, but for retaining the spring in place, as well, In addition, it will be noted that the spring section ofthe hinge lies interiorly of the supporting section, and carries a suitable lug for retaining the spring substantially under normal tension, independently of the supporting section.

Referring now to specific'e'mbodiments of my invention; that of Fig. Iv comprises a spring-section a and supporting-section respectively adapted to be screwed to the door andthe door frame. Two lugs a b are bent up interiorly at either end of said sections for the purpose of forming the knuckle of the hinge. The lugs a are centrally punched or flanged to produce inturned ferrules a, which extend within and serve to retain the spring a '1n place. On the upper lug there is also provided an out wardly extending lug a2, which extends besiel hind the protruding end of the spri g and ribbed both for the purposes of ornamenting and strengthening the hinge sections.

Little explanation is necessary for the purpose of understanding the construction. of Fig. II, which closely `resembles the one alreadyv described. It may be pointed out, however, that the lugs a b are bent up exteriorly of the hinge blank proper, and the iet t had] ltremities of each hinge sectiong better adapting: said hinge for certain purposes. In the modiication ofFig VIII, moreover, the construction already described is folloWed out with the 'addition of a partial overturned flange @4,adaptedlto engage the exterior of a larger and heavier spring than those shown in the foregoing figures, for the purpose of retaining it' in place. Thisila'nge, of course, will be provided above and below, and may be used alone or in addition to the in-turned ferri'ile a.

It Will'noW be understood that a door mounted with my improvedspring hinges, may be readily removed .upon taking. out the removable pins, and, as indicated,- this is particularly desirable With screen doors, Which require storing during al largepor.- tion of the year. Again, the expanded or extended bearings aiforded for the stamped metal hinge bythe integral ferrules orilanges a 2), greatly improve a deviceof' this class, While the spring retaining means found in the iii-turned ferrules, the lug a",

and the"lip a4, are practically essential in.

equivalent `form, to a removable-or loose-pin Springhinge.

y 'Having now described certain embodiments of my invention, I claim and desire to secure by Letters Patent, the follovvingzy l. rilhe combination in a hinge, With' tWo leaves having stamped metal lugs extending at right anglestherefrom; the said'lugs having ferrules or angesformed respectively upon the opposite sides thereof, of a' pintle' extending through said errules and having bearing surfaces therein, substantially as set forth.

2. In a separable spring hinge, the combination with two hinge sections `formed of stamped metal, having co-acting lugs bent at right angles from the bodies thereof, and a rearwardly-positioned 'retaining-'lip on one of said4 sections, of a spring mounted upon the latter section and retained under normal tension by said lip, and a removable pintle pivotally uniting said `lugs for assembling the hinge sections, substantially as set forth.

3. In a stamped metal hinge, the combination With two integral hingeI sections, comprising co-acting leaves having pivoting lugs bent substantially at right angles there.- to in twodifferent planes; of engagement, fitting one Within the bther; the said lugshaving ferrules respectivelyformed' there.- on extending on either side of said planes of engagement to form Widely separated bearings, of a pintle egrtendingthrough said ferrules and pivotally mountingsaid hinge sections, substantially as set forth. i

5. In a spring hinge, the-combination with twoseparable hinge sections, of a spring permanently mounted vupon one of saidv vhinge sectioii's; rth` e latter having integral engaging parts for retaining the spi-ing" under normal tension, 'and a removable' pintle tor separably mounting the hinge sections, substantially as set lforth.

6.

7 In a spring hinge, the combination with two separable hinge sections formed ofstamped metal and having. lugs bent 'at right angles from 'the bodies thereof, spring` mounting members and a retaining lip upon one of said sections for maintaining the spring ,under tension, of .av spring mounted under normal initial. tensionv upon said'seca with a lip lfor retaining the spring under substantially normal tension, of said spring mounted between the lugsy and ferrules one or' said sections and retained under tension by the lip, and a removableL piiitle tending through said lugs and ferrules for pivotally connecting the hinge sections, substantially as set forth.

` 9.
